PHYSIOLOGIC SIGNAL MONITORING USING ULTRASOUND SIGNALS FROM IMPLANTED DEVICES
First Claim
1. A method for determining one or more time-varying physiologic parameters within the body of a patient using intrabody ultrasound signals, comprising:
- receiving an ultrasound signal transmitted from a remote device located within the body, the ultrasound signal including encoded sensor data measured by the remote device;
transducing the ultrasound signal into an electrical signal;
decoding the sensor data from the electrical signal and generating a first physiological waveform corresponding to the sensor data measured by the remote device; and
generating a second physiological waveform by analyzing fluctuations of the electrical signal caused by physiologic modulation of the ultrasound signal during propagation through the body.

Abstract
Devices, systems, and methods for monitoring and analyzing physiologic parameters within the body using an intrabody ultrasound signal are disclosed. An illustrative method includes receiving an ultrasound signal transmitted from a remote device containing encoded sensor data, converting the ultrasound signal into an electrical signal, decoding the sensor data from the electrical signal and generating a first physiological waveform, generating a second physiological waveform by analyzing fluctuations of the electrical signal caused by physiologic modulation of the ultrasound signal during propagation through the body, and analyzing one or more characteristics of the first and second waveforms to determine one or more physiologic parameters within the body.
